Feminising Cannabis Seeds, a vital Step in Cannabis Cultivation.
Recognizing the distinctions Between Male and female seeds for a successful harvest.
In this article, we’ll delve into the fundamentals of male and female seeds and discuss methods for feminizing them to achieve a superior yield.
First we need to know what are Male and Female Seeds?
Cannabis plants are categorised as either male or female, each fulfilling distinct roles in their growth cycle.
Male plants generate pollen, whereas female plants yield buds or flowers which contain higher levels of THC.
To produce seeds, the male plant must pollinate the female plant.
When cultivating marijuana for medicinal or recreational use, growers generally seek to exclude male plants and focus solely on cultivating female plants that yield buds.
What are Feminized Seeds?
Feminized seeds are seeds meticulously bred to yield only female plants.
This is accomplished through a technique known as “feminizing,” which entails altering the genetics of a female plant to guarantee the production of female seeds.
Why Use Feminized Seeds?
There are numerous benefits to using feminized seeds, including:
Higher success rate: Feminized seeds ensure that every seed will yield a female plant, eliminating the possibility of male plants emerging in the garden.
Efficient space utilization: By exclusively cultivating female plants, growers can optimize garden space and maximize their crop yield.
Consistent quality: Feminized seeds result in a uniform quality of buds from each plant, promoting a more consistent overall harvest.
So how do we Feminize Seeds?
There are three primary methods for feminizing cannabis seeds: the rodelization method, chemical treatment, and colloidal silver.
We will explore each method below!
1) Rodelization Method
The rodelization method for feminizing cannabis seeds is a natural technique that leverages the plant’s survival instincts.
This method is appealing to many growers due to its simplicity and the fact that it doesn’t require special chemicals or equipment.
However, it’s important to note that while rodelization is natural and straightforward, it’s also considered less reliable compared to other methods like using colloidal silver or silver thiosulfate.
First Step for the rodelization method is to select a healthy female plant.
The process commences with the selection of a vigorous female cannabis plant.
Ideally, this plant should be 3-4 weeks into its flowering phase and display a well-balanced combination of leaves and buds.
Prolong the Flowering Stage:
In contrast to other methods, rodelization involves allowing the female plant to prolong its flowering stage beyond its usual harvest time.
This prolonged period induces stress in the plant, potentially triggering the development of male pollen contained in pollen sacs.
Monitor for male flower development:
During the extended flowering period, closely observe the plant for the emergence of male pollen sacs or sex organs.
This occurrence as a natural response to the stress of not potentially remaining unpollinated.
Collect and Utilize the Pollen:
Once the male sacs reach maturity, harvest the pollen they contain. This pollen, predominantly female genetically, can then be employed to pollinate other female plants.
The resultant seeds are expected to be feminized.
Harvest the Seeds: Following successful pollination, permit the plants to complete their growth cycle until the seeds reach maturity and are ready for harvesting, this process can take up to 6 weeks or more until the seeds are fully mature to harvest.
It’s crucial to acknowledge the potential drawbacks of the rodelization method.
For instance, not all cannabis strains will inherently exhibit male characteristics when subjected to stress.
Additionally, there’s a risk of fostering hermaphroditic traits in subsequent generations. Moreover, the quantity of pollen produced may be considerably less than what’s obtained from conventional male plants.
Despite these drawbacks, rodelization continues to be a preferred option for individuals seeking a more natural method of producing feminized seeds, particularly among organic growers.
Chemical Treatment Method.
The Silver Thiosulfate (STS) technique is a sophisticated and effective approach for feminizing cannabis seeds, particularly suitable for home growers and professional breeders seeking reliable results.
Here’s how it works.
You need to purchasing STS solution.
While preparing the STS solution entails a complex chemical process, it’s more convenient for home growers and breeders to purchase ready-made STS solutions. This approach not only saves time but also ensures the correct concentration and composition of the solution, which is crucial for effective treatment.
Before proceeding with the application process, it’s crucial to emphasize the importance of safety.
When handling STS you need to wear protective gear, including gloves and safety glasses. It’s essential to remember that plants treated with STS are not suitable for consumption and should be handled accordingly, do not ever handle this liquid directly on any part of your skin, eyes or mouth.
The application of applying the STS spray/liquid is a delicate process.
This solution should be sprayed onto the plant, focusing primarily on the nodes and bud sites. The optimal time for the initial application is just before transitioning the plant from its vegetative stage to the flowering stage.
Subsequent applications are necessary every few days until the emergence of male flowers, indicating the effectiveness of the treatment, usually 2 sprays is enough.
After the first plant has had it’s spray, place the plant in the dark for 24 hours, you can place a black bag over the plant to black it out for 24 hours, or put it in a dark room for 24 hours before it enters into it’s 12/12 light cycle for the first time.
After 7 to 10 days spray the plant again and place it back in the flowering 12/12 light cycle room.
Once the male flowers develop and begin producing pollen, this pollen is used to pollinate other female plants.
Following successful pollination, the seeds which develop on the female plant are harvested after 8 weeks.
These seeds are 100% feminized, with a high probability that 99.9% will grow into female plants.
Make sure that you dispose of STS-treated plants carefully.
After you have finished with these plants, these plants should not be consumed, burn them in your garden or in your wood fireplace.
If you have made it this far! then you are breeding cannabis seeds.
This method unlocks opportunities to develop your own strains by cross-pollinating different plants, facilitating a fusion of desired traits and characteristics.
Feminise and make seeds of all your favourite strains.
Colloidal Silver Method
Colloidal silver is a solution of pure silver particles suspended in distilled water.
It’s widely utilized in health applications and is available for purchase online or from health food stores.
In cannabis plants, colloidal silver impedes ethylene production, essential for the plant to produce female flowers.
Instead, the plant forms male pollen sacs.
When you are preparing and starting the Process:
Select a robust female cannabis plant to serve as your “mother” plant.
This plant should display desirable traits as it will contribute to the genetic makeup of the feminized seeds.
Application of Colloidal Silver:
The colloidal silver solution should be sprayed onto the plant, concentrating on the branches where bud development is desired.
This application should occur during the vegetative stage of the plant.
It’s advisable to use a colloidal silver solution with a concentration of at least 30 PPM (parts per million) for optimal effectiveness.
Thoroughly spray the plant, ensuring all intended areas are covered, and continue this process daily for approximately 10 to 21 days, starting when you switch to a 12-12 light cycle. For auto-flowering strains, more frequent application may be necessary.
Development of Male Pollen Sacs:
Following regular application of colloidal silver, the female plant will begin to develop male pollen sacs.
These sacs contain pollen with female genetics. Once these sacs begin to swell and the leaf section protecting the pollen starts to crack, they are ready to be harvested.
Pollen Harvesting
Gently collect the pollen sacs and allow them to dry in a cool, dry location. The pollen can then be utilized to pollinate other female plants.
The seeds produced from this pollination will be feminized.
Safety and Disposal of used pollen plants:
It’s crucial to understand that any part of the plant treated with colloidal silver is not safe for consumption.
After the pollen is collected, the treated plant should be discarded.
Additionally, ensure thorough cleaning of any equipment used to prevent accidental contamination with colloidal silver.
The pollination of female plants:
After obtaining the male pollen, you can pollinate a female plant of your preference.
This can be achieved by isolating the plant or branch you wish to pollinate and applying the pollen, such as using a Q-tip.
The pollinated plant should then be allowed sufficient time to produce viable seeds, which can vary from 6 to 8 weeks depending on the strain.
